Evaluation Of A Bamboo/Epoxy Composite As A Potential Material For Hybrid Wind Turbine Blades
The use materials such as wood as a load bearing structural member in wind turbine blades is primarily limited to small wind turbines or in a limited number of large blades manufactured from birch with glass and carbon-fiber reinforcement. The limited supply and high cost of birch has led to a search for other renewable materials that can be used for wind turbine blades. Bamboo has many engineering and environmental attributes that make it an attractive material for utilization in wind turbine blades. This paper examines the mechanical properties of a novel bamboo-poplar epoxy laminate which is being developed for use in wind turbine blades. Information provided in this brief paper include an overview of the laminate construction and initial data for the monotonic tensile and compressive stress-strain behavior of panels formed by hot-pressing. In addition, a discussion of fracture resistance of the bamboo-poplar laminate, under Mode I and Mode II loading conditions is provided. General recommendations regarding the future use of bamboo-based composites for large MW size wind turbine blades are also presented.
